Answer 1

mysql_fetch_array() returns an array containing both associative keys (the field names specified by queries) and integer position key (i.e. 0 is first field, 1, is second, etc.). This is for convenience in accessing the data by either method.

if you only want the named keys, you should use mysql_fetch_assoc() or better yet, use the mysqli functions as everyone on here will lambast you for using the old mysql_* functions.
